. 'This invention is directed ,to an improvement in diapers of aninexpensive disposable type, constructed in a manner to be readilyconformable is directed along definite channels lengthwise of thegarment and thus prevented from seeping through the edges of thenarrower width 4and at the same time lmaterially increasing theabsorptive capacity.

20 The description is directed to a specic embodiment, more particularlyshown in the accompanying drawing, wherein: l f

Figure 1 is a perspective view of the garment.

Fig. 2 is a transverse section of the same. .25 Fig. 3 is a brokenperspective view showing the various layers of the garment.

Fig. 4 is a view illustrating the application of the garment. v

The improved garment is constructed with an 30 inner layer l of finegrade gauze which has been treated preferably for softness andnon-absorbency. A lm of high grade absorbent cotton 2 is applieddirectly against the outer surface of the gauze, the effect of which isto make the 35 gauze materially softer upon skin contact and y thusless` irritating. Beyond the lm of cotton there is applied severallayers of absorbent cellulose 3, these layers forming the absorbentelement. Beyond the absorbent element there is 40 arranged an outerlayer of waterproof paper I. The edges of the gauze layer l areextended-over the side edges of all layers, as at 5, except the outerlayer, passed beneath or inwardly of the outermost layer of theabsorbent element, and

45 secured firmly to the outer layer of waterproof paper by Aadhesive orlike means, indicated at 6.

Securing tapes 1 are applied to the outer side of the paper layer andextendy beyond the sidel edges of the garment to permit securing thegar- 50 ment about the body of the infant as indicated in Fig. 4. Thegarment is applied with the longitudinal side edges passed between thelegs, the

^ respectiveY ends of the garment encircling the body, whereby theprojecting' ends of the tapes 55 may be tied to secure the garment inplace weith- (Cl. 12S-284) out liability of slipping and without the useof the usual safety pins-or like fastening means. The tape connection isat the waist line and directly above each hip.

As the garment is necessarily of greater length 5 than width it wouldresult, in the absence of special provision, that the absorptivecapacity without leakage would be governed by the width, for themoisture would saturate the absorptive element in all directions andthus reach the sides more quickly than the ends. To avoid this and tomaterially increase the absorptive capacity without increase in size,the/ respective layers of the cellulose absorptive element are providedwith lines of Wax or like material, as at 8, extending more or less inparallel direction longitudinally i of the garment. These lines functionas guides for the moisture and tend to d irect it longitudinally of thegarment, and thus the. length of the garment rather vth its widthgoverns the absorptive capacity wi out leakage. l

Where the absorptive element is of crepe formation', the tendency of thesame is to direct the moisture toward the side edges, and -this stendency is directly opposed by the lines through which'v the moisturedoes not pass, and by which the accumulated moisture is compelled totravel longitudinally of the garment.

The capacity of the garment for moisture absorption is thus materiallyincreased without 30 leakage, and as the outer layer is waterproof.there is no tendency to leak therethrough, and thus the usual outergarment of rubber or the like is unnecessary.

The garment is one in which the various layers may be readily assembledby machinery if desired, thus further reducing the cost, a desirableitem 'as the garment is to be disposed of after use. It is completelysoft and non-irritating; has the maximum absorptive capacity incident toits 40 size; is generally prooi` against leakage through its edges evenunder maximum moisture conditions; is waterproof against outer garmentsworn next to it: and is so inexpensive to manufacture as'to render itadvantageous to 'use in comparison 45 with other garments designed forthe same purpose.

Having described the invention, what is claimed as new isz-- 1. A-bodygarment comprising a casing for that facing vwhich comes nextthe bodyconstructed of soft-textured, conformable, permeable materialland havingoutlying portions constructed of fluid-repellent material, and a fillingcomprising laminated sheets. of soft porous cellulosic matel 55 rial,vwith spaced apart wax stripings extending longitudinally of the sheetsfor the purpose and with the result of preventing escape of uid at thesides of the garment without impairing nor--V mal ow through thefilling.

2. An article as deilned in claim 1, in which the plies are so arrangedthat the wax stripings are in substantial registry.

3. A pad for absorbing body fluids having on lanes defined by thestripes.
